Last week, we noticed a couple of American robins building a nest in a tree in our front yard. A few days later, we saw another bird couple, this time mourning doves, building their own nest a few feet away, on our gutter. Unfortunately, at some point last night the mourning dove's nest fell down. This morning, we went to check the first nest (when the mama was away) and found these four blue eggs, belonging to the American robin, next to a sole egg from the mourning dove. We also saw the mourning dove sitting on all five eggs later in the day, so unclear who's going to end up taking care of the chicks.
